BX25D/BX23S Swivel Seat problems

[aussiealex]

Hey mates, I've got a BX25D with one serious and one annoying issue with the swivel seat.

1. The seat "pops out" on the right side pin where the latch is that releases it to lift up and swivel around. Has anyone had this issue? I can't pin point the problem..it seems like the whole mechanism has loosened up everywhere and allowing too much play for the pin to pop out.

2. There is a little sliding pin that locks the seat in the upper midway position between backhoe and front loader. I've seen most videos online where people simply push the seat one way or the other and this acts as a "notch" to temporarily hold the seat up. However mine "locks" the seat there and I have to manually push the sliding mechanism up to allow the pin the slide forwards or backwards successfully.

Any ideas?

On my BX23S had #2 problem this summer. A good cleaning and spraying some red Rustcheck(liquidy waxy oil ) solved that . Reminds me I need to spray the BH pivots under the cover today....

Assuming I understand your problem correctly, check to see if the 4 white plastic spacers on the swivel plate have fallen out. Two of mine did, and that allowed the swivel plate to sit lower on one side, causing the latch not to engage. The part I'm referring to is #K2591-56670 seat spacer. Hope this helps.

Great tip mate, I'm going to go and have a look now. Perhaps this is it. Sounds like my issue as one side tends to not 'pop out' and sits better. I've got a video of the problem I posted on a facebook group, but it's a Kubota Australia group and won't let you access unless you're a group member. This forum doesn't seem to allow videos?

@Grampus I've managed to upload the video to youtube: https://youtube.com/shorts/3UUAmzc65c8?feature=share

I also took a look at the spacers and they are still in place.

In your video (thanks for posting it) something looks odd at the two front corners to me. The far side is outside the frame and the nearside is inside the frame. That just looks like both should be on the same side (inside or outside).

But I have no idea how it is really su to be, it just looked odd and like it could be the reason it can come apart.

Good luck!

Thanks for your idea. I think this is how it's designed. I'll go have a look. I think you remove a Cotter pin and slide the whole mechanism sideways to remove/replace. That's how it's designed..

Is the spring (250) broken or missing or not attached properly (under tension)?

Is part 240 swiveling freely? Otherwise maybe add a drop of oil on each pivot point.

Sorry I couldn't help. If I think of anything else I'll let you know.

You are correct about removing the whole mechanism. However, I highly recommend removing the seat first, then if necessary you can remove the support mechanism. The reason being that entire assembly weighs a ton! If you accidently drop it or let one side slip, you could easily puncture the fuel tank. Also, it is extremely difficult to realign the two pins by yourself when you want to re-install the mechanism. I had to get my wife to help. Much easier to remove the seat first- just 4 easily accessed nuts at the four corners. That removes about a third of the weight.

That is how it is supposed to look. The entire support/swivel mechanism is attached to the mounting brackets by two 1/4 inch pins about 1 1/2 inches long. You line the pins up with the holes in the bracket on the left side, then slide everything to the right. A clip holds it in place ( I believe they call the clip a snap pin).

Hey mate, Spring 250 is not broken or missing and is under tension.

Is the spring (250) broken or missing or not attached properly (under tension)?

Is part 240 swiveling freely? Otherwise maybe add a drop of oil on each pivot point.

Good tip, thanks. Happy to remove the seat if needed. May not be a bad way to diagnose a bit by removing some of the weight.

Hey Hugo, Thanks - spring 250 is totally fine. Its quite tight and the latch comes up under the spring tension and feels right. I did inspect it. The R clip beside the spring is also in place and holding things in place as it should. I unfortunately can't see part 240 in your diagram (it's cut off). Where did you load up this image? I can go check. I assume it is swiveling freely - perhaps a little too freely

#240 is shown in the diagram above but here it is again (just below the #250 balloon) in green highlight.

@Hugo Habicht - sorry to barge in but I thought the global time difference between your two continents may be a stumbling block to progress!

Hi,

I got that from a parts diagram on messicks.com
Kubota has similar parts catalogues online, but I cannot open them from my location.

You say 240 is missing, but this is the bar you move in the video. Is that really spring loaded pushed downwards at the front?

If yes, maybe the hooks are worn and you need a round file to bring them into shape again.

 

[GreensvilleJay]

great.... NOW I know what's missing on my BX23S seat, that #250 spring ! The bar came off as the clip #255 went MIA.yeesh, I put TWO R-pins on,even though picture shows only one.
I need to start writing a 'todo' list,have couple other things to add,though I've forgotten what they were.
sigh, getting old sux .

I just looked at this picture again, and a thought came to me. I can see that the spacers are still there, but I can't see how worn they are. If they are worn down too much, especially if one side is worse than the other, it will let one side drop down. You should be able to look between the two metal plates from the edge. If you decide to take the plates apart, beware that there are two ball bearings between them (you can see them in the picture) that can fall out once they are separated. The spacers are very inexpensive if you need to replace them (about $5 for a bag of five).
